Application filed September The present invention relates .to doormountings, and particularly to door mountings adapted for use on stoves.

One of the principal objects of the present invention is to provideconcealed means for supporting a door and urging it towards closedposition.

. Another object is to provide yielding door closing means soconstructed as to maintain its effectiveness when employed on apparatussubject to relatively high temperatures; and to permit ready access tosuch means for adjustment or repair, without disturbing the setting ofthe stove.

A still further object of the invention is to provide normally concealedmeans for sup-' porting or hinging a door.

Other objects of the invention will be apparent from the followingdescription when taken in. connection with the accompanying drawings inwhich:

Fig. 1 is a fragmentary vertical section through the body of a stoveembodying the present invention, the false side wall being omitted forclearancein illustration; and

Fig. 2 is a section on the line 22 of Fig. 1. Referring to the drawingsdenotes theside wall of themai-n body portionyof the stove which isprovided with upper and lower compartments or ovens 21 and 22, it beingunderstood that the stove has suitable burners or heating means, notshown, for heating the oven or compartments in the usual manner. Thestove illustrated is of the type adapted to receive gas burners andthese may be placed in the upper part of compartment 22 and when thusplaced the com artment 22 constitutes a broiling oven and t 1ecompartment 21 constitutes a baking oven. It will be understood,however, that the particular location of the burners or heating devicesma be va-- ried widely, and that the location of t e burners isimmaterial with respect-to the present invention.

The main body portion of the stove of course comprises suitable top,bottom, and

side walls, the side wall being illustrated at 20 and the bottom wall at23. A horizontal partition 24 generally divides the body into the upperand the lower compartments above mentioned. The side wall of the stoveis provided at its front with door openings 25 and 26 which are ada tedto be covered by the upper door 27 and t e lower door 28, respectively.The bottom wall 23 is here illustrated as hav- 2, 1925. Serial No.54,036.

ing its outer edges turned downwardly to form flanges 30 which may bereinforced at the corners by reinforcing members 31, to

which reinforcing members may in turn be attached the supporting legs32.

The door openings 25 and 26 may be provided with inturnc'd flanges 35,which, as

shown in Fig. 2, are spaced from the side walls 20 of the ovens.Pivotally mounted as at 36 upon each side flange of the lowercompartment 22 is a bell crank lever 37 one arm 38 of which extendsupwardly and is erably attached to the flanges 35 to provide a fluespace, in which flue space the door supporting mechanism is positioned.The upwardly extending arms of the bell crank lever 38 together withtheir forwardly projecting ears 39 constitute supporting members for theupper door 27. Hook ear members 41 extending rearwardly fromthe rearfaceof the door at each end adapted to hookover pivot pins 42 extendinglaterally from the portions, 39 of the supporting members, form apivotal connection between the door and its supporting members. The bellcrank lever 37 is also rovided with a rearwardly extending arm 45 avingan aperture 46 by which it may be connected with tension rod 47 of ayielding means which normally tends to rockthe bell crank lever 37 insuch a direction as to draw the supporting member and its ear 39inwardly, to thus urge the door 27 toward closed position. The lower end-of the tension rod 47 passes through an aperture 48 in the bottom Wall23 to the relatively cool space below the compartment 22. Surroundingthe lower end of'the tension rod 47 is a coiled spring 49 which bears atits upper end against the bottom wall 23 of'the lower oven and which isengaged at its lower end by the wing nut 50 screw threaded upon thetension rod 47, to permit of varying the closing tension of the spring.

The supporting means for the lower oven door 28 is generally similar tothat described above for the upper door. It will be noted, however, inthe case of the lower door, that the arm 38 of the bell crank lever 37extends downwardly from the pivot and that the car 39 which is now atthe lower end of the arm wardly through an aperture 56 in the lower artof the oven 22. The long arm 38 of the hell crank lever is provided withan aperture 57 corresponding with the aperture 46 in the short arm 45and spaced substantially an equal distance from thepivotal support 55.Owing to the reversal of position of the bell crank lever which supportsthe lower door, the tension rod 58 of'the yielding means is engaged inaperture 57 instead of in aperture 46, as in the case of the upper door.The tension rod 58 is extended downwardly through an opening 59 in thelower wall 23 of the oven, and this Wallis formed or bent downwarly toform an abutment 60 for the upper end of coil spring 61 surrounding thelower portion of the tension rod 58. Wing nut 62 screw threaded upon thelower end of the tension rod 58 engages the lower end of compressionspring 61 and serves to place the com ression sprlngunder compression orto ad]ust such compression." Spring 61,

like spring 49, tends to draw inwardly the supporting member to which itis attached.

The connection between the. lower door 28- and its supporting member issimilar to that between the upper door and its supportingv member and,therefore, need not be further described.

The operation of the invention may be best understood from Fig. 1 inwhich the lower door'28 is closed so asto show one extreme position ofthe supporting members, and the upper door 27 is open so as to show theother extreme position of the supporting members. It will be observedthat when the door is moved from its closed position towards its openposition, it-fulcrums about the lower edge 63 of the door and draws ear39 of the supporting member outwardly, the lower,

edge of the door meanwhile sliding upwardly on the front face of theoven until the inner edge or face of the door'comes into engagementwiththe lower edge of the supporting ear '39, as indicated at 64. Thisrelation of the parts is shown by the door 27, and it willbe observedthat the door-is stopped in a substantially horizontal position andapproximately at the level of the partition 24 orming the bottom wall ofthe oven 21. In moving the door to its open position the spring 49 is,of course, placed under additlonal compression. While the door is beingclosed the spring draws the arm or supportas a fulcrum the closing meansthen placing a relative force upon the door to urge the upper parttightly against the body of the oven.

An important'feature of the present invention resides in the fact thatthe springs 49 and 61 are readily accessible for readjustment,inspection, or replacement. lleing below the bottom wall 23 of thestove, the springs and their adjusting nufs can be easily reachedwithout the necessity of moving the stove away from the wall ordisconnecting the gas pipes. Further, the location of the springs in theposition shown, removes the necessity for placing such springs in therear or at the sides of the stove where they form unsightly projectionsand interfere with the placing of the stove against the wall of theroom. In addition the springs are located completely outside of the ovenand are so. mounted as to be not subjected to destructive heatinfluences.

Although the door is connected with its supporting member merely througha hook and pin connection, as illustrated, the door is neverthelesssecurely held in position for when the door is open, as illustrated at27. I

the pin 42 is held in the hook 41, and when the door is closed, asindicated at 28, then the hook 41 is likewise locked againstdisengagement from the pin 42. To enable the removal of the door, thesupporting car 39 is .provided with an opening 65 through which a nailor other tool may be inserted while the door is fully pen so as toprevent the supporting ear from being drawn inwardly by the spring.Then, by merely raising the door to its vertical position, the hook 41and pin 42 may be disengaged, and the door thus removed.

7 Another feature of the invention is the construction and arrangementof the parts such that the bell crank lever 37 may be usedinterchangeably either in supporting an upper door, as illustrated, orfor supporting a lower door. The bell crank lever with its laterallyextending cars 39 and 45 is of a general Z shape and is adapted, merelyby inverting its position, to support upper or lower doors.

In the manufacture of this part it is preter-' ably provided with twoapertures'46 and 57 for receiving the tension meaps in whicheverposition the supporting means may be used. In this connection it is tobe noted that the lever arm from the fulcrum ot the member 37 to eitherof the attaching apertures 46 or 57 is considerably shorter than thelever arm between the fulcrum of the member 37 and the point ofattachment of the door at 42. The extent of movement of the tensiondevice attached either at 46 or at 57 is thus considerably lessthan themovement of the pin 42 and as a consequence there is a comparativelyshort movement of the tension rod and of the spring of the yieldingmeans,

whichis an advantage in that it enables a reduction in length and insize of the spring and the associated parts.

While the form. of apparatus herein described constitutes a preferredembodiment of the invention, it is to be understood that the inventionis not limited to this precise form of apparatus, and that changes maybe made therein without departing from the scope of the invention whichis defined in the appended claims.
